All pictures are gone

[doorofperception]

Hello Layers,

I hope somebody can help me.
The website of a customer is shattered all of a sudden:
 www.practice.de

It happened without me doing anything. I haven't logged in to the site for about a week.

All images across the site are not displayed anymore.
Everything looks normal in the backend. The Menu is still visible.
On mobile also all the text is gone. I only see the title bar but also the menu doesn't show.

WHAT COULD THAT BE?
I would greatly appreciate any hints, since I'm absolutely clueless where to start even.

Thanks so much.
BEN
